Both UK companies will use a system called Travelsafein order to be able to determine what hotels must be blacklisted or not. I know for a fact that in the past Opodo also partnered with Travelsafe in order to perform health and safety audit with its hotels.
According to Travelmole, Lowcostbeds.com and OnHolidayGroup will use the system to be able to blacklist the hotels, apartments and villas that does not satisfy the new standards; I have no information about those specific standards yet, but there will be a focus on safety standards in such areas as fire, food hygiene, and swimming pools.
About child safety, upon completion of the audit, Travelsafe will classify hotels into 4 categories: Gold, Silver, Bronze and the ones that are said to be non compliant.
It will be offered the possibilities to assist hotels that are said to be non compliant to implement the necessary improvements. If they refuse, there will be “blacklisted and banned from all Travelsafe member sites.”

This new “hotel trend” for safety accommodations got its root from last September tragedy when two young children past away from carbon monoxide poisoning in Corfu. I found an article of the Independent (London) reporting that the mother of the two children was highly motivated to push the industry leaders to take measures to prevent such tragedies in the future. It seems that she has been heard!

There are already “no fly” lists, I guess a “no-stay” list is a logical next step in the industry..

If British OTA are about to blacklist hotels, Australian hotels already blacklist guests

I have seen several different types of blacklisting in the past:I have read about hoteliers in Australia who blacklist “bad” guests on a dedicated website launch on December 2006: Guest Behaving Badly GBB. Its product manager Josh Ginty said “more than 1000 holiday property providers nationally have already joined the database.

The rationale behind this hotel trend?“Customers have the ability to rate hotels with websites such as TripAdvisor.com. So why shouldn’t hotels be able to rate customers?” as reported by Daniel J. Solove in a very interesting article called “The rise of customer blacklists”.
